JOHN M. VVAKEMAN, OF WATKINS, NEW YORK.

SL JLKY-DRAG.

SPECIFICATION forming part of Letters Patent No. 235,832, dated December21, 1880.

To all whom it may concern Be it known that I, JOHN MORRIS WAKE- MAN, acitizen of the United States, residing at Watkins, in the county ofSchuyler and State of New York, have invented certain new andusefullmprovements in Sulky-Drags and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

This invention relates to certain improvements in sulky drags orharrows; and the novelty consists in the novel construction andcombination of parts, as will be hereinafter more fully set forth, andpointed out in the claims.

Figure 1 of the drawings is a plan view of the improved sulky-drag. Fig.2 is a side sectional view of the same, taken through the line an 00 ofFig. 1. Fig. 3 is a perspective View of one of the bars with its tooth,upright pin, and strap-collar. Fig. 4 is another perspective view of oneof the bars, showing the tooth at an incline, and a modification of thestaple or strap coupling.

In the annexed drawings, forming a part of this specification, theletter A represents the axle; B B, the wheels, and O the tongue or polewith the diagonal brace-rods 0t, securing a firm connection between saidtongue and axle.

The letters D D are a series of drag-bars, the bars D being longer thanthe bars 1). Each drag-bar, at or near its rear end, is provided with abarrow-tooth, the teeth being set at an incline, as seen in Figs. 2 and4 of the drawings. By this difference in length in the drag-bars I amenabled to arrange them alternately in series of long and shortdrag-bars, as shown in Fig. l of the drawings.

The axle A is provided with a series of grooves or recesses, b, toreceive the straps or staples or clevis c, pivotally attached at theforward ends of the drag-bars. These straps or staples fit loosely inthe grooves or recesses in the axle, so as to allow an upward movementand a sidewise or lateral motion of the Application filed September 28,1880. (No model.)

drag-bars, which movements of the bars are caused by the unevenness ofthe ground surface and small obstructions in the nature of clods andsticks, also stumps. These straps or staples or clevis 0, pivoted to thedrag-bars, serve a twofold purpose-first, to allow the drag-bars, in theharrowing process, to rise and fall, conforming with uneven surface ofthe soil; and, second, to permit a side motion, either right or left, tothe bars. This compound motion allows the drag-bars to readily yieldvertically or laterally when coming in contact with an obstacle orobstruction, thereby saving the teeth from injury and clogging andresistance to draft.

The upper rear end surface of each dragbar is provided with a verticalpin or upright rod, [1, in front of the tooth, as seen in the drawings,to prevent riding or crossing of the drag-bars upon each other while thedrag is in operation or in turning in the field. Whenever a drag-bag isthrown upward and sidewise its tendency is to cross and ride theadjacent bar; but the employment of a vertical rod on each bar obviatesthis difficulty by guiding the bar off and causing it to resume itsnormal position for duty.

Fig. 4 of the drawings represents a modification of the coupling meansin making the connection between the bar and axle, which consists in astrap and a staple for producing substantially the same result.

The operation and advantages of the dragbars, with the two rows of teetharranged in different planes, are obvious and need no furtherdescription.

I claim the right to vary the construction and the coupling meanswithout departing from the spirit of the invention.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. Adrag-barhavin g a metallic loop pivotally attached thereto, incombination with an axle having a cylindrical bearing, whereby acompound motion is secured to the drag-bar, substantially as set forth.

2. In a drag, the combination of a plurality of drag-bars of diiferentlengths having a compound motion-to wit, vertical and lateralandprovided at their rear upper surface with vertical pins or rods toprevent crossing or riding of the adjacent drag-bars, substantially asdescribed.

3. In a drag, the combination of an axle having a series ofjournal-bearings and a series of drag-bars having at their forward endsswivel-loops and at their rear ends harrow-teeth and vertical rods orpins, for the purposes hereinbefore set forth.

4. In a drag, adrag-bar having a compound movement, vertical andlateral, substantially as described.

5. A drag mounted on Wheels, consisting of the axle A, formed with aseries of bearings,

the drag-bars D, of different lengths, alternately arranged, andprovided at their upper ends with pivoted loops 0, and the vertical rodsd at the upper surface of the rear end of the drag-bars, substantiallyas shown and de- I scribed. y

In testimony whereof I affix my signature in presence of two Witnesses.
